Shift Kit help
 

My cousin put a shift kit in a 700R4. From first to second it shifts very frim and lurches forward. but from 2nd to 3rd it sort of hits a neutral or slipps inbetween the shift (motor revs up), then goes into 3rd. Being a passenger in the truck I can't even feel it shift into OD. I wasn't there when he put it in, but he's positive he did everything 100% correct. Anyone else had this problem or know a solution?

What kit did he use? Name, stage, etc..

Please say its notta B&M shiftkit !!!

My blazer 700R4 did the same thing,

I found out later from the tranny shop, that the mechanic that bought it from them, installed it wrong and was out of adjustment.

I only drove it a few weeks, but in that short time I had burned up some things in the tranny and it had to be replaced.

This time I had the tranny shop do it and they were mad at the other mechanic so they didn't charge me they charged him for his mistake.

Mine does this too without shift kit. Funny thing is it seems to do it more while turning?

What is wrong with a B&M?

I think it was a B&M. Not sure of the stage. NVbowtie what was installed wrong in yours?

I have heard way way too many bad experiences with them. As far as shift kits. Oh yeah and they like to eat parts and brake things internally.

Guess I would buy a shifter from them but thats about the only thing I would buy from them. :bowtie:

sounds like the converter,or the bands i would take it to a tranny shop let them testdrive it .b&m products are fine

B&M shift kits will most of the time, kill a 700R4. They are fine in 350's or 400's, but I sure wouldn't install one in a 700.

Check out Team Chevelle on there bb in the transmission fourm and see what they all have to say about b&m. They have atleast 3 transmission builders that I have seen that posted negitive things about B&M shiftkits. Its only1/3 of a kit and its not even a good one at that.

I don't recall for sure but I think it was the bands were burned, it slipped due to TV cable not adjusted right and some thrust bearing????

Sorry I am not a tech, and they tossed all these terms to me and all I cared about was, that I ended up - not - having to pay for it.

B&M products used to be fine. after all of the big company buyouts, i think their quality has really gone south. same with TCI.

I guess TH700s need to be beefed up to handle a shift kit. I'm surprised mine has gone 136,000 miles with no problems. Of course, I can hit 80mph and still be under 2000 rpm! I hit 85 mph and I'm at about 2150rpm. At 65 I'm only at 1400. :D But it STILL gets 10mpg! This 305 is getting tossed soon. I was beat by a F*rd diesel yesterday!
